Matthew Hernandez January 7‚ 2015 Gango – 2 Practice AP Essay In an excerpt from Lady Windermere’s Fan by Oscar Wilde‚ the playwright reveals the values and nature of his own society through the conduct of his characters. The author uses the lives of high-class people to demonstrate the underlying fancies and motivations of the elite society of his time. Wilde targets the society’s emphasis on an external show of good behavior‚ their scorning of the lower classes‚ and their vanity in living for the

I am choosing to study how the PSI (pounds per square inch) of a football is affected by the temperature. I chose to study this because I like football and I always pondered this question. I believe that this is a worthwhile question to study because these studies can help improve the game as the weather gets colder. As air cools‚ it expands‚ so when a football gets colder‚ the air inside it expands. This expansion causes the air pressure to decrease. The air pressure decreases because the molecules

Abstract This experiment was designed to answer the question does temperature affect the amount of osmosis? The hypothesis predicted was that the higher the temperature the more osmosis would occur‚ but too high the osmosis would halt due to enzyme and substrate overheating and losing shape. After research and class time it was concluded that osmosis is a passive transport and would not require energy or enzymes due to it going from high to low concentrations with the gradient

When a beetroot cell is exposed to various kinds of temperatures‚ its plasma membrane is affected and may change in structure resulting in the leaking of betacyanin. If the temperature changes‚ then I would expect to observe that there would be a change in the concentration of betacyanin that has leaked from a beetroot cell. In specific‚ at high temperatures‚ the phospholipids that make up the plasma membrane of the beet root cell become progressively more destabilized causing them to transform into

Appreciate how a physical property that varies with temperature may be used for the measurement of temperature‚ and state examples of such properties. Recognise the need for and identify fixed points. Describe the structure and action of liquid-in-glass thermometers. Demonstrate understanding of sensitivity‚ range and linearity. Describe the structure of a thermocouple and show understanding of its use for measuring high temperatures and those that vary rapidly. 1. A clinical thermometer

Investigating the effect of temperature on plant cell membranes The purpose of this activity is: • to practise experimental and investigative skills • to investigate the effect of temperature on cell membrane structures Procedure SAFETY: Always carry scalpels clasped to a tile and with the tip pointing away from you. Beetroot cells contain pigments called betalains that give the tissue its dark purple-red colour. The pigment is contained in the cell vacuole. Investigation

changes in enzyme function? Objective The objective of this experiment is to observe if changes in temperature will cause a disruption in enzyme function. Hypothesis If we add and boil enzyme in L-Dopa‚ then the color will become darker because the temperature will denature some of the enzymes. Variables Independent: Temperature Dependent: Color change Control: Time‚ Room temperature Jobs We were assigned different jobs to perform the experiment Janelee had two jobs because we were

should include placebo-controlled trial in this specific situation‚ we should analyze this problem in three steps. (1) List out the various options that we could perform to arrive at the final purpose. (2) Determine all the foreseeable benefits and harms that could result from each action for everyone that could be affected by the action. Cost-benefit evaluation might help in

The Effect of Increasing Temperatures on the Enzyme Catalase Enzymes are proteins that help speed up chemical reactions inside your body and without enzymes‚ chemicals reactions in cells would be incredibly slow to a point where no activity at all takes place (Brawo press Inc‚ 2017). Enzymes speed up the chemical reactions by lowering the activations energy and they do this by binding substrates together in the correct orientation to react (Ernest Z‚ 2014). They are vital for life and serve a
